base plate when the anchor bolts are loaded in tension Different behaviour should be considered when strength stiffness and rotational capacity of the base plate loaded by bending moment have to be predicted see 1 The column base stiffness is in particular influenced by behaviour of the tension part of the base plate see 2 Design of Column Base Plates Typical column bases as shown below consist of a single plate fillet welded to the end of the column and attached to the foundation with four holding down bolts The bolts are cast into the concrete base in location tubes or cones and are fitted with anchor plates to prevent pull out HighRectan and a design example is given gular base plates are obviously suitable for steel columns with 1 or W sections Circular base plates are commonly used for pipe columns such as pylons in cable stayed bridges lighting poles Analysis of Circular Base Plates with Large and electric power line posts 6 8 2020 nbsp 0183 32 Design Example Verify the capacity of the base plate arrangement in grade S275 steel shown below to resist the following actions M Ed 125 kNm N Ed 870 kN compression V Ed 100 kN Column From data tables for 254 x 254 x 132 UKC in S355 Depth h c 276 3 mm Width b c 261 3 mm Flange thickness t f c 25 3 mm Web thickness t w c 15 3 mm3 2 1 Example Concrete Slab on Columns 14 3 2 2 9 4 1 5 Column Pinned Base Plate 187 9 4 2 Rigid Connections 189 9 4 2 1 Fixed Base Plate 189 9 4 2 2 Welded Moment design of tension members including wire ropes round bars and compound tension members
